Metribuzin and Pendimethalin effects on weed dynamics, crop growth and yield of wheat
A field experiment conducted at Agricultural Research Farm, Division of Agronomy, BHU, Varanasi to evaluate the efficacy of herbicide to control of weeds in wheat crop. Weed flora of the experimental field was dominated by broad leaved weeds like Solanum nigrum, Anagallis arvensis, Chenopodium album, Vicia sativa, Melilotus indicus, Rumex dentatus, and Medicago denticulatum, narrow leaved weeds like Cynodon dactylon, Phalaris minor and sedges like Cyperus rotundus. In the experimental field weeds were controlled by pre-emergence application of herbicides viz.,pendimethalin 30% EC @ 600 g ha-1, pendimethalin 30% EC @ 900 g ha-1, pendimethalin 30% EC @ 1200 g ha-1, pendimethalin 30% EC @ 1500 g ha-1, metribuzin 70% WP @ 210 g ha-1and weed free (two hands weeding). All herbicidal treatment compare with Untreated Control (Weedy check). Among all herbicidal treatment pendimethalin 30% EC @ 1200 g ha-1 application is effective to control Phalaris minor, with WCE was 89.21%. Metribuzin 70% WP @ 210 g ha-1 have efficacy to control broad-leaf weed effectively and some narrow leaf weed. The highest grain yield observed in hand weeding (5693 kg ha-1) followed by herbicidal treatments, pendimethalin 30% EC @ 1200 g ha-1 (5078 kg ha-1). Highest B: C ratio (2.11) is achieved with the application of pendimethalin 30% EC @ 1200 g ha-1.
Design and experimentation of an intelligent control system for a small self-propelled electric transplanter
The purpose of this paper is to design an intelligent electric transplanter to improve the efficiency of greenhouse vegetable transplanting and the accuracy of precise plant spacing.kernel technologies of the transplanter include mechanical design, adaptive fuzzy PID control, and Android terminal control. The main body of the mechanical part is composed of the seeding cups and the hanging cup type planetary wheel planting mechanism. An adaptive fuzzy PID algorithm is proposed to accurately control the rotating speed of the driving motor and the working motor, and simultaneously, the driving device and the planting device are perfectly matched. In experiments with transplanting frequency of 30-40 plants per minute, transplanted seedlings spaced 30-40 cm apart, and a controlled rate of 40 plants per minute, it was found that the maximum and average control errors of the transplanter's motor speed are respectively 12.76% and 10.83% if the motor speeds are between 20-40 rpm. When compared with a conventional PID controller, the adaptive fuzzy PID controller can reduce the maximum and average control errors by 6.8% and 6.25%, respectively. Moreover, the average error rate of planting spacing, the maximum error rate of line spacing, and the success rate of transplanting are respectively 6.21%, 13.37%, and 95.67%. the control software of the mobile phone is utilized to conduct state detection and transmission to the cloud. The position of the transplanter can be monitored online and the travel speed, transplanting speed and transplanting spacing of the transplanter can be adjusted in real time.

The present investigation comprised of 28 F1s developed by crossing 8 lines viz., K - 9107, HD – 2733, HD – 2888, WH – 1218, K – 1313, DBW – 187, HD – 3086, and DBW – 107 following half diallel mating design. The 36 genotype (28 F1s + 8 Parents) were sown in Randomized Block Design with three replications in timely sown (TS) condition. On the basis of per se performance and GCA effects good general combiners were DBW – 107, K- 9107 and K- 1313 for days to 75% heading , HD – 2733 and K- 1313 for plant height, DBW – 107, K- 1313 and DBW - 187 for days to maturity, HD – 3086 and HD – 2733 for number of tillers per plant, HD – 2733 and HD – 2888 for number of spikelet’s per ear, K- 9107, DBW – 187 and DBW - 107 for ear length, K- 9107, HD – 2733 and HD – 2888 for number of grain per ear, WH – 1218, DBW – 187 and HD - 3086 for 1000 grain weight, DBW – 187 and HD – 3086 for grain yield per plant. Good common cross combiners on the basis of SCA effects and per se performance were HD - 2888 / K – 1313 for plant height, K - 9107 / HD – 3086 and HD - 3086 / DBW – 107 for number of tillers per plant, WH - 1218 / DBW – 187 and WH - 1218 / DBW – 107 for ear length, HD - 2733 / K – 1313 for 1000 grain weight, K - 9107 / WH – 1218 and HD - 2733 / HD – 3086 for weight of grain per ear, HD - 2733 / DBW – 187 and DBW - 187 / DBW – 107 for grain yield per plant. In the present study, fifteen crosses showed highly significant and negative economic heterosis in desirable direction was observed in K - 9107 / K- 1313, K - 9107 / DBW – 187 and K - 9107 / HD – 3086 for days to heading. Four crosses showed the significant and negative heterosis as HD - 2733 / K – 1313, HD - 2733 / DBW – 187 and K - 1 313 / DBW – 107 for plant height. Three cross showed significant and positive heterosis as K - 9107 / HD – 3086 and HD - 3086 / DBW - 107 for more number of tillers per plant. One cross showed significant and positive heterosis K - 9107 / K- 1313 for number of spikelet’s per ear.

Studies on variability in Seedling Tree Population of Pecan nut [Carya illinoensis (Wang) K Koch.] for nut and kernel characteristics in Jammu and Kashmir
Survey was undertaken to explore the existing variability in Pecan [Carya Illinoensis (Wang) K Koch.] of seedling tree origin in Jammu province for utilization its potential in future breeding programmes. Out of total seedling tree population in the region 60 healthy and bearing trees were marked to access the available genetic variability in pecan nut germplasm. Based on the characterization and evaluation of nut and kernel characteristics pecan trees excelled in major economically important characteristics. All the 60 seedling trees exhibited extreme variation for individual traits. The results revealed that nut shape in ventral view varied from circular to ovate, nut shape in cross section varied from narrow oblate to circular, shape of apex from lateral view varied from rounded to acute, length of tip varied from short or absent to long, area covered by spots on nut varied from small to large, kernel adherence to shell varied from weak to strong and intensity of brown colour in kernel varied from light to dark.
Impact analysis in carbon footprint of equally nutritional vegan and omnivorous diets
The relationship between the food consumed daily and its impact on the environment is extremely close, even more when it is obtained either from animal or plant sources. This analysis aimed to assess the carbon footprint of different diets and subdiets belonging to the omnivorous and vegan diets that have emerged recently, such as the plant-based diet, the conventional vegan diet, the Mediterranean diet, and the average Chilean diet, to determine their Greenhouse Gas emissions (GHGE), through the equivalent mass of CO2 (kg CO2e) produced throughout the life cycle of each product belonging to each of these diets. From the proposition of nutritional minutes of equal caloric content for each of these diets, it was possible to quantify the GHGE, thanks to the values obtained through different programs and bibliographic reviews on the subject. It was concluded that at equal caloric and nutritional value, the plant-based subdiet was the one that clearly generated the lowest carbon footprint, due to the preference of plant over animal products in the diet minute. The Chilean average subdiet showed the higher CHGE, about 160 % greater than the plant-based subdiet.
